[0030] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0031] Example 1
[0032] like Figure 1 As shown, this embodiment provides a ventilation pipe assembly, including a heat exchange pipe 11 and a screw 12. The screw 12 is embedded in the heat exchange pipe 11 to form a spiral channel. By adding a screw inside the heat exchange pipe, the channel inside the heat exchange pipe is extended in a spiral shape, so that the length of the airflow channel inside the heat exchange pipe is much longer than the length of the heat exchange pipe, which is beneficial to improving the heat exchange efficiency of the heat exchange pipe.
[0033] like Figures 1-3 As shown, the above technical solution also includes an upper support 13a and a lower support 13b. The heat exchange tube 11 is arranged vertically. The upper support 13a is embedded in the upper inner end of the heat exchange tube 11, and the lower support 13b is embedded in the lower inner end of the heat exchange tube 11. The screw 12 is located between the upper support 13a and the lower support 13b, and both ends of the screw 12 are connected to the upper support 13a and the lower support 13b respectively. Both the upper support 13a and the lower support 13b are provided with air passage holes 131 that pass through vertically. By adding the upper and lower supports, and connecting the two ends of the screw to the upper and lower supports respectively, it is more convenient to install the screw inside the heat exchange tube.
[0034] See details Figure 1 and Figure 2As shown, the above technical solution also includes a film-opening ring 14, which is embedded in the upper inner end of the heat exchange tube 11. The outer diameter of the middle and lower ends of the film-opening ring 14 is reduced to form an annular liquid distribution cavity 15 with an annular gap-shaped opening at the lower end between the ring and the heat exchange tube 11. The heat exchange tube 11 is provided with seepage holes 111 that communicate with the annular liquid distribution cavity 15. (Multiple seepage holes 111 with the same horizontal height can be arranged circumferentially at corresponding positions on the heat exchange tube, so that the liquid film distribution on the inner wall of the heat exchange tube is more uniform.) The upper end of the upper support 13a is connected to the lower inner end of the membrane opening ring 14, and the air passage 131 on the upper support 13a is connected to the interior of the membrane opening ring 14. This allows liquid to flow into the heat exchange tube through the seepage hole. The liquid entering the heat exchange tube will be distributed downward in a ring shape in the annular liquid distribution chamber and flow downward along the inner wall of the heat exchange tube to form a liquid film on the inner wall of the heat exchange tube. The liquid film evaporates with the airflow under the heat of the heat exchange tube to further cool the heat exchange tube, thereby further improving its cooling effect.
[0035] like Figures 1-3 As shown, in the above technical solution, a liquid storage core layer 16 is provided on the inner wall of the heat exchange tube 11, located below the opening ring 14. By providing a liquid storage core layer on the inner wall of the heat exchange tube, the liquid film on the inner wall of the heat exchange tube can be distributed more quickly and evaporate more quickly. The increased amount of evaporated liquid can carry away more heat.
[0036] In the above technical solution, the upper end of the liquid storage core layer 16 extends into the annular liquid distribution cavity 15, so that the liquid in the annular liquid distribution cavity can be distributed in a liquid film form on the inner wall of the heat exchange tube more quickly.
[0037] The liquid storage core layer 16 described in the above technical solution is a cylindrical wire mesh component, which has a simple structure and high thermal conductivity.
[0038] like Figures 1-3 As shown, the heat exchange tube 11 in the above technical solution is provided with heat exchange fins 112 on its outer wall, which can further improve the heat exchange efficiency of the heat exchange tube.
[0039] like Figure 2 and Figure 3 As shown, in this embodiment, the upper support and the lower support are provided with an embedding groove 132 at the middle of their respective ends. The two ends of the screw are respectively inserted into the two embedding grooves. In this embodiment, the edge of the screw extends to the inner wall of the heat exchange tube, which can prevent the airflow from flowing directly upward in a straight line along the inner wall of the heat exchange tube.
[0040] Example 2
[0041] like Figure 4As shown, the embodiment provides an air-cooled radiator, which comprises a cabinet 2 and the ventilation pipe group 1 as described in Embodiment 1. The cabinet 2 is sequentially provided with an upper air chamber 21, a liquid permeation chamber 22, a cooling chamber 23 and a lower air chamber 24 in the up-down direction. The cabinet 2 is provided with an air outlet 211 communicating with the upper air chamber 21 and an air inlet 241 communicating with the lower air chamber 24. The cabinet 2 is provided with a liquid inlet interface 221 communicating with the liquid permeation chamber 22 and a liquid inlet 231 and a liquid outlet 232 communicating with the cooling chamber 23. The ventilation pipe group 1 is vertically arranged in the cabinet 2 and penetrates the liquid permeation chamber 22 and the cooling chamber 23. The two ends of the heat exchange pipe 11 respectively communicate with the upper air chamber 21 and the lower air chamber 24. The liquid permeation hole 111 is located in the liquid permeation chamber 22. In this way, the hot fluid can be introduced into the cooling chamber, the airflow is introduced into the upper air chamber through the ventilation pipe group after entering into the lower air chamber, and is finally discharged. The airflow is cooled by the heat exchange pipe group in the process of passing through the ventilation pipe group. In addition, the liquid is introduced into the liquid permeation chamber, the liquid in the liquid permeation chamber enters the heat exchange pipe through the liquid permeation hole and is finally evaporated to absorb the heat on the heat exchange pipe, thereby further improving the cooling effect of the ventilation pipe group on the hot fluid.
[0042] In the embodiment, the air inlet 241 communicates with the fan. The fan blows air into the lower air chamber. The airflow enters the upper air chamber through the ventilation pipe group and is finally discharged through the air outlet 211. The hot fluid enters the cooling chamber through the liquid inlet 231 and is discharged through the liquid outlet 232. In this process, the heat of the hot fluid is transferred to the airflow, the hot fluid is cooled, and the temperature of the airflow increases. In the embodiment, the liquid can be supplied into the liquid permeation chamber 22 at the liquid inlet interface 221 (the liquid can be water at room temperature). At this time, the liquid in the liquid permeation chamber permeates into the heat exchange pipe through the liquid permeation hole and diffuses downward on the inner wall of the heat exchange pipe in the form of a liquid film. The liquid film is evaporated and discharged upward into the upper air chamber with the airflow in the diffusion process. The focus of the embodiment is to combine air cooling and evaporation cooling to cool the hot fluid. The cost is low, and the cooling efficiency is high.
[0043] In the embodiment, the amount of liquid introduced into the liquid permeation chamber should be balanced with the amount of liquid permeated. It is preferable that the amount of liquid permeated at the liquid permeation hole does not overflow into the heat exchange pipe in the form of a jet.
[0044] In the embodiment, the heat exchange fins are located in the cooling chamber, which can increase the contact area between the heat exchange pipe and the hot fluid.
[0045] In this embodiment, three partitions 25 can be arranged sequentially in the vertical direction inside the cabinet. The three partitions divide the cabinet into an upper air chamber 21, a seepage chamber 22, a cooling chamber 23, and a lower air chamber 24, which are distributed sequentially in the vertical direction. The ventilation pipe group passes through the three partitions 25.
[0046] The ventilation duct assembly 1 described in the above technical solution is provided in multiple units, which makes the cooling effect of the hot fluid in the cooling chamber better.
[0047] In the above technical solution, the liquid inlet 231 is connected to the lower inner end of the cooling chamber 23, and the liquid outlet 232 is connected to the upper inner end of the cooling chamber 23. This allows the hot fluid to be discharged in the form of overflow in the cooling chamber, so that the hot fluid can be cooled more fully by the ventilation pipe assembly.
[0048] The thermal fluid described in this embodiment can be a gaseous fluid or a liquid fluid.
[0049] in, Figure 3 The dashed arrows in the diagram indicate the path of airflow through the upper support into the membrane opening ring and finally discharged into the upper air chamber; Figure 4 The dashed arrow in the diagram represents the airflow entering the heat exchange tube from the lower air chamber through the lower support.
[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
